Atlanta pulled away by outscoring the Bobcats 34-19 in the second quarter.
Teague split two defenders to covert a three-point play at the 3:35 mark of the second to make it 53-39.
Driving from left side of the perimeter, Teague left his feet for a layup, but had his first attempt nearly blocked. He pulled the ball back down, though, and floated toward the baseline to bank in the shot.
Smith, who followed with a 20-foot jump shot at the 2-minute mark to give the Hawks a 16-point lead, beat Eduardo Najera for a defensive rebound in the final minute and made a one-handed pass to Johnson at halfcourt. Joe Johnson passed to Ivan Johnson for dunk that made it 59-42.
D.J. Augustin started for the 39th time in his 41 games despite falling and hurting his left knee in the Bobcats' five-point loss Tuesday at Toronto. Augustin, who managed just two points in less than 11 minutes, was already battling tendinitis in his right knee.
